Widespread and affordable mobile broadband access opens up opportunities for delivery of new streaming services everywhere and anytime. However, what is expected to fundamentally change the way how people use the network is the ability to produce, and seamlessly deliver and share their own multimedia content. In this paper we describe the content distribution and adaptation architecture that we have implemented and tested, the results utilising new coding formats of video coding (e.g. SVC, MVC) and new methods for increasing the robustness of video delivery.

Traditional point cloud compression (PCC) methods are not effective at extremely low bit rate scenarios because of the uniform quantization. Although learning-based PCC approaches can achieve superior compression performance, they need to train multiple models for different bit rate, which greatly increases the training complexity and memory storage. To tackle these challenges, a novel FoldingNet-based Point Cloud Geometry Compression (FN-PCGC) framework is proposed in this paper. Firstly, the point cloud is divided into several descriptions by a multiple-description Generation (MDG) module. Then a point-based Auto-Encoder with the multi-scale Feature Extraction (MFE) is introduced to compress all the descriptions. Experimental results show that the proposed method outperforms the MPEG G-PCC and Draco with about 30% similar to 80% gain on average.

Widespread and affordable broadband access opens up opportunities for delivery of new streaming services. However, what is expected to fundamentally change the way that people use the network is the ability to produce, and seamlessly deliver and share their own multimedia content. SEA consortium is confident that in a few years everyone will be multimedia content producer, mediator and consumer, and aims to provide the means to distribute A/V user-centric services, with superior quality and flexibility, in a trusted and personalized way.
